Quoting Stormjay Rider
Hey Andros/Pittstop, I noticed you gave an answer in the MOCpages help about embedding videos. However, that isn't the end of the case: a lot of builders have been embedding video, which is embeddable, as background music. Do you know if this is permitted?

Simple answer, yes you can, BUT as was discussed in the link I gave in the MOChelp group, Sean prefers video to be about LEGO or the MOC, random pop videos might be pushing the rules a little.
